STAY-STRIP.

Specification of Letters Patent.

Patented Jan. 19, 1909.

Application filed November 23, 1905. Serial No. 288,661.

To all whom fit may concern:

Be it known that I, JAMES RICHARD CAR- TER, citizen of the United States, residing at Newton, in the county of Middlesex and State of Massachusetts, have invented a certain new and useful Improvement in Stay- Strips, of which the following` is a specifi-- cation, reference being had therein to the accompanying drawings.

In the making of paper boxes, in which a stay-strip is employed to bind together two adjoining sides of the box, the strip is glued or pasted partly to one of said sides and partly to the other, and has to be bent at a right angle in order to lap from one side onto the other. In order to make a neat piece of work, it is necessary to bend or fold the stay-strip on a line parallel with its sides and preferably along a median line. When the stay is put on by machine, it is common to crease the strip along the intended folding line in order to enable it to be accurately folded. Sometimes this is done by means of a creasing device connected with the machine which applies the stay to the box, that is by running the at strip over a creasing device just before it reaches the box.

The object of this invention is to provide a gummed, uncreased stay-strip, said strip being marked by a dotted line before being put up so as to indicate the folding line, and

y to assist in properly bending the strip during the operation of the machine by which it is applied to the box.

In carrying out my invention I make preferably in the ungummed face of the strip a row of dots or slight indentations separated from each other, but all in the line on which the strip is intended to be folded.

The invention will now be fully described, and the novel features thereof will be particularly pointed out in the claims at the close of the specification.

In the drawings,-Figure l is a plan view of the ungummed side of a stay-strip embodying the invention. Fig. 2 is a longitudinal section along the line of indentations, the thickness being considerably enlarged to more clearly illustrate the invention. Fig. 3 is a perspective view, showing the strip partially applied to the corner of a box. Fig. 4 is a perspective view of a roll of uncreased material embodying my invention.

Referring now to the drawings,-The stay-strip l is composed of cloth or paper or other suitable material, and has upon one face a coating 2 of adhesive material of suitable composition which may be applied in any well known way, and then dri-ed. After the adhesive has become sufficiently dry, a row of dots or independent minute indentations 3 are made lengthwise of the strip, preferably in the ungummed face thereof, along the line where the stay is intended to be folded. By making the dots or indentations in the ungummed face of the strip, the latter may be more conveniently'and accurately applied, the work of the operator being facilitated thereby. These dots may be made by a marking or printing wheel or by any other suitable instrument. The special means by which the dots are made is not material. The strip is not, however, creased or folded in any manner at this time. It is kept flat in cross section, and may be put up in rolls or other convenient form for ready use.

It will be found that a strip thus constructed can readily and accurately be bent along the indicated line when it is run over the creaser at the time of being used for application to the box.

I'Vhat I claim is:

l. A roll of uncreased material adapted for a corner stayV strip for boxes and the like having upon one face a coating of adhesive material and having on one face a line of dots impressed thereon longitudinally of the strip and parallel with the sides to indicate the line on which the strip is to be folded, the body of the strip and the lm of adhesive where the dots occur being undiminished from the rest of the strip, both faces being unbroken and imperforate.

2. A corner stay strip for boxes and the like having upon one face a coating of adhesive where the dots occur being undiminof one face a line of dots longitudinally of the strip and parallel with the sides to indicate the line on which the strip is to be folded, said dots being impressed upon the surface in such manner that the material is unbroken and undiminished, and the backing and adhesive being the same in amount according to area against the dots as in the undotted portion.

3. A roll of uncreased material adapted for a corner stay strip for boxes having upon one face of the body a coating of uniform thickness of adhesive material and having In testimony whereof I atIiX my signature 1n presence of two Witnesses.
